run code in 300+ PHP versions simultaneously
<?php class Test { const t = __CLASS__.' foo'; const d = dirname(__DIR__); } var_dump(array( __DIR__, Test::t, Test::d, ));

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
